SHIP-PROTECTOR.

Application filed July 24, 1918.

To all wfiom may concern:

Be it known that I, JOHN GLINKA, a citizen of Russia, residing at Wilson, in the county of Allegheny and State of Pennsylvania, haveinvented certain new and useful Improvements in Ship-Protectors, of which the following is a specification.

rl`he primary object of the invention is the provision of adjustable outrigger members adapted for stabilizing a ship as well as protecting the hullV thereof against injury from oncoming missiles, the device being serviceable at either side of the hull and also adapted for preventing other ships from contacting and damaging the hull.

A further object of the device is the provision of an outwardly positioned protector carried by a hull positionable horizontally when not in use, but readily projected to an inclined position partially immersed in the water when desired as a guard against torpedoes and other missiles.

With these general objects in view. the device consists in the novel combination 'and arrangement of parts hereinafter fully described in connection with the accompanying drawings and in which like reference characters designate corresponding parts throughout the several views.

In the drawings,

Figure 1 is a top plan View of a hull partially broken away with my device installed thereon;

Fig. 2 is a Vertical transverse sectional view of the same;

Fig. 3 is an enlarged view partly in section and partly in elevation showing one set of Operating gear connections;

Fig. 4 is a Vertical sectional view thereof;

Fig. 5 is another Vertical sectional view of the same taken upon a different plane from the line of section of Fig. 4.

Referring more in detail to the drawings, my invention will be illustrated in connection with the hull 10 of a ship designed to be protected from oncoming nnssiles by means of my invention. A perforated armor plate 11 is adjustably carried ateach side of the hull 10 for partial immersion in the water after the manner of an outrigger. Each plate 11 is provided with two arms 12 having a hinge connection 13 with a rack 14 slidably mounted upon rollers 15 within a tubular rectang'ular casing 16 extendmg specification of Letters Patent.

transversely of the hull lO-and projecting outwardly of one side thereof.

The racks 14 of each plate 11 are adapted for slmultaneous operation by means of gears 17 carried by a shaft. 18 journaled longitudinally within the hull 10, it being evident that upon turning the shaft 18 in opposite directions, the racks 14 will be moved inwardly and outwardly of the casings 16 imparting a corresponding movement of the arms 12 and the plate 11 carried by the said arms. Cables 19 are attached as at 20 to the plate 11 and pass over sheaves 21 provided in openings 22 of the hull 10 and thence over idlers 23 within the hull for winding upon drums 24 carried by a shaft 25 positioned longitu'dinally of the hull above the shaft 18.

A stub-shaft`26 is journaled adjacent one end of the shaft 25 having a pinion 27 in constant mesh with a gear 28 upon said shaft 25. The stub-shaft 26 is journaled in slots 29 in bearing posts 30 while the reduced ends 31 of the shaft 25 are journaled in slots 32 in posts 33 positioned adjacent the opposite ends of said shaft When the pinion 27 and gear 28 are in their lowered positions with the shafts 25 and 36 lowered, the gear 28 will be in mesh with the gear 17 of the shaft 18 so that upon turning the crank 34 of the stub-shaft 26, theracks 14 will be reciprocated simultaneously with the unwinding of the cables 19 from the drums 24 when the racks 14 are being projected and winding up the cables 19 upon. said drums when the racks 14 are being retracted.

It is desirable, however, to permit the arms 12 and its plate 11 to lower into the water at an inclination when the racks 14 are projected7 and this is permitted by disengaging the gear 28 from the gear 17 by means of plates 35 adapted for Vertical movement upon the posts 33. Such disengagement of the gear 28 from the gear 17 also permits the arms 12 to be elevated to their horizontal positions, as indicated by dotted lines in Fig. 2 of the drawings, prior to retracting theracks 14 with the said arms 12. The plates 35 have the reduced ends 31 of the shaft 25 journaled in perforations 36 of said plates while bolts 37 carried-by the posts 33 freely extend through llmltlng guide slots 38 provided through said plates.

An Operating` lever 39 is provided for each plate 35 being pivoted thereto asat and also pivoted to a braclt 41 carried by the adj acent post 33. y

The racks 14 are normally retracted as Well as the arms 12 and atA which times the plate 11 will be vertically positioned adjacent the outer free ends 4C2 of the casin'g's 16 slightly spaced from one side of the hull 10. The pinion 27 being' in mesh with the gear 28 and the latter meshing' i'vith the gear 17 it Will' be seen that upon turninp; the Crank 341 in the required dir'e'ction, the shaft Will be revolved for un'vvinding the c-ables 19 from the drums While the gears 17 project the racks 14: outwardly of the cating` 16. `When the plate 11 is at the outwar'd limit of its mo-vement, the `levers 89 Will be depresse'd for elevating the plates carrying' the shaft 25 and stub-shaft 26 therewith and dis'engaging the gears' 17 and 28. r1`he orank 34 may then be turned for permitting a further' unwinding' of the eables 19 from the drums 2% allowing'the plate 11 to lower to the desired eXtent into the water at the side of the hull 10. 1t Will be understood that by substantially revers- 'mg' the operation just described, the plates 11 may be elevated positioning the arms 12 horizontally in alinement with the raoks 14, and upon releasing' the levers 829 the crank 81 may be turned for reversely revolving the gea rs 17 to invvardly move the r'acks 1a while the drums 24 are simultaneously. revolved for Winding up the oables 19. Rack por' tions 4:3 are provided for the ar'ms 12 fornr ing' continuations of the racks 14 for meshing With the gears 17. Then retracti'ngz,` the arms 12, the levers 39 may be held downwardly in any desired manner for maintaining' the plates 35 elevated, and When the arms reach the horizontal positions7 the levers 39 may be released for continuing' the operation of the Crank 84:. An adjustable bearing' block is preferably provided Within each slot 29 of the post 30 for bearing` upon the stub-shaft 26 when the same is depressed, therebymaintaining the shaft 25 in its lowered position and the pinion and gears in meshing relations. Op erating screws et5 are provided for said' blocks 114 and whereby the blocks 114; are readily elevated When it is desired to elevate the stub-shaft The'plates 11 are designed to beat least thirt-y feet outwardly of the hull 10 When operatively positioned and to eXtend a sufficient depth beneat-h the surface of the Water to be hit by torpedoes traveling' at. their usual level toWard the hull v10. The contaoting 'of one of the plates 11 by a torpedo is designed for explo'ding the torpedo while it is also designed to stop the forward moveinent of other oncoming' inissiles or projectiles, and the distanee at which the plates 11 are positioned from the hull 10 is designed to be sufficient to prevent any injury to the ship by reason of such explosion or contact.

A strong` protector is provided for the hull 10 which Will not impede the travel thereof When the plates 11 are pivoted, While the said plates afiiord means for preventing a boat of the enemy from contact-ing the hull 10 in Whatever position vthe said plates 11 may be located. Eachp'late 11 is operated separately by dentcall 'the same form of mechanisni and one plate'` niay be el'evated while' the' other piatejll is' lower-ed. The tr'ansverse casin'gs 16 for the' ra'eks le o'fthe opposite plates 11 are preferably formed after the manner of a double ca'sing' as' best illust'rated in Fig; 3 of'the' drawin'gs and With the separate' c'asing portions'projecting through the opposite side's of the hull 10'for accommodating the ra'cls and arms' of' the opposite plates 11.
